Answer:
Step-by-step explanation:
We are asked to write 77.7% as a decimal.
We know that percent means per hundred.
To write 77.7% as decimal, we will divide 77.7 by 100 as:
Move decimal to left by two digits.
Let us set 0.777 equal to x as:
We can see that our decimal has three 7 digits after decimal, therefore, 1 digit is repeating after decimal.
Answer: Is the ratio between two directly proportional quantities
Answer:
Answer is the ratio between 2 directly proportional quantities
To solve a quadratic equation in the form you can use the quadratic formula:
In your case, the equation is identified by the coefficient choice , so the solving formula becomes
As you can see, we have a negative number under a square root, an operation impossible to perform using real numbers. So, this equation has no real solutions.
Answer:
The number of years that will the two villages have the same number of residents is 61 years
Step-by-step explanation:
Let's assume number of years as 'x'
First Pond:
Fresh pond has a population of 854
and it’s increasing by 3 people per year
so, we can find equation for population of first pound
Second pond:
Strawberry has a population of 427
and it’s increasing by 10 people per year
so, we can find equation for population of first pound
Since, populations are equal
so, we can set both equation equal and then we can solve for x
So,
The number of years that will the two villages have the same number of residents is 61 years
